Overview
The MMBZ5228BS-7-F is a dual isolated Zener diode array manufactured by Diodes Incorporated, housed in an SOT-363 surface-mount package. It features a nominal Zener voltage of 3.9 V with a tolerance range of 3.71 V to 4.10 V at a test current of 20 mA. The device supports a maximum power dissipation of 200 mW and operates within a temperature range of -65 °C to +150 °C. Electrical specifications include a maximum Zener impedance of 23 Ω and a maximum reverse leakage current of 10 μA at 1.0 V.
Feature Summary
- Dual isolated Zener configuration integrated into an ultra-small surface mount package
- Planar die construction designed for automated assembly processes
- Lead-free plating with matte tin finish annealed over Alloy 42 leadframe
Applications
- Voltage regulation circuits requiring dual independent channels
- Clamping applications for signal lines
- Protection circuits in compact electronic devices
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging details. Confirm that the component meets RoHS compliance requirements and matches the intended thermal and electrical specifications for the target application environment before finalizing procurement.
Selection Notes
Select this component when a dual-channel Zener solution is required in a minimal footprint. Ensure the circuit design accommodates the 200 mW power dissipation limit and verify that the 3.9 V breakdown voltage aligns with the system's protection or regulation thresholds.
Part Context
This part belongs to the MMBZ5221BS through MMBZ5259BS series, which provides various Zener voltage options in the same SOT-363 package. The series utilizes a standardized marking code system where 'KG3' identifies the 3.9 V variant. All parts share identical mechanical dimensions and mounting characteristics.
Replacement Considerations
Direct substitutes within the same series include other MMBZ52xxBS variants if different voltage ratings are acceptable. Verify pinout compatibility and ensure the replacement maintains the dual isolated configuration and SOT-363 package form factor.
